Fire Opal Cleavage
When it comes to choosing the best pick among Red Gemstones gemstones, Fire Opal is known to be a popular choice!Physical properties of Fire Opal include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Fire Opal Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Fire Opal cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Fire Opal is 1.97-2.22.
The physical properties of Fire Opal, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Fire Opal is represented by SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001) More from other references.
